Modified Files:
	src/sys/arch/hppa/hppa: db_interface.c trap.S

Log Message:
Improve ddb backtraces by:

	- Starting with the right set of fp, pc, and rp in all cases.
	- Dropping the argument printing stuff as it could never work.
	- Backtrace through traps and decode syscalls properly by
	  making sure the trapframe is at a known offset from the stack
	  pointer in both cases. Also, ensure that the frame pointer
	  is zero so that we can detect traps.
